F. J. GREMEL BRACED MOLD "WALL Filed Jan. 26, 1929 2 Sheets-Sheet g mvEN'rdR ATTORNEYJ Patented Sept. 15, 1931 UNITED STATES. PATENT OFFICE FRANK J. GREMEL, OF DETROIT, MICHIGAN; CAROLINE GREMET. EXECUTE/IX OF -SAID FRANK J. GREMEL, DECEASED i BRACED MOLD WALL v Application filed January 26, 1929. Serial No. 335,213.

The present invention pertains to a novel wall erected as part of a concrete mold or form, and the principal object is to provide bracing members for a wall of this character assembled from a set of panels.

The panel assembly is similar to that shown in my United States Patent No. 1,641,927 of September 6, 1927, and the mold walls are spaced and tied by a device similar to that disclosed in my Patent No. 1,607,072 of November 16, 1926. These ties extend between and through the pair of walls forming any part of the mold and are provided with heads at the outer sides of the walls. Bracing rods are connected between the heads, being preferably laid diagonally of the panels, and wedges are driven between the panels and the adjacent rods for providing contact between these parts. In order to brace the walls at the intersections of the edges of the panels,

certain of the bracing members are extended across these intersections and brought into contact with the latter by means of wedges in the manner already described.

The invention is fully disclosed by way of example in the following description and in the accompanying drawings, in which Figure 1 is a fragmentary side elevation of a mold wall erected and braced according to the invention;

Fig. 2 is a plan view thereof; and

Fig. 8 is a fragmentary vertical section thereof.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

As usual, the mold consists of two spaced and opposed walls, each of which consists of a number of panels 1 properly assembled.

' The panels are provided at their edges with strips 2 and 3 by means of which a joint is formed. Further, the panels carry inter-engaging fastening elements 4 and 5 which are drawn and held together by wedges 6 passed therethrough. At the upper edge of the wall,

the fastening elements 7 have upwardly extending pins 8 over which are passed lower angle bars 9 and upper angle bars 10 which respectively lap over alternating vertical joints between the panels.

The opposed walls are spaced by means of tie members, each of which includes a conical body 12 between the walls, necks 13 passing through the walls, and heads 14 at the outer surfaces of the walls. orked wedge members 15 are driven over the necks in order to bind between the walls and .the adjacent heads 14, whereby the walls are clamped into engagement with the ends of the body 12. p

The heads are drilled diametrically as at 14, and bracing rods 166 with reduced ends 17 have their ends passed through the heads.

These rods are preferably laid diagonally of the panels and are of such length as to lie within the edges of any given panel. Another set of bracing rods 18 is however-provided and has itsends drilled at 19to receive the reduced ends 17 of the aligned rods 16,

whereby to form a continuous diagonalex tending over several panels. The members 18 are preferably located to extend across the corners of adjacent panels for a purpose which will presently appear.

Additional contact points for giving better effect to the braces areprovided by means of l forked wedges 20 driven between the outer surfaces of the mold walls and the adjacent bracing members. These wedges are not nec essarily forked, but are preferably made in this form and similar to the forks 15 in order to reduce the variety of parts. Thus the wedges 20 which engage the bracing mem bers 18 are preferably caused to close the corners of adjacent panels in order to rein force these corners where buckling is most What I claim is 2-- 1. A braced mold wall comprising a plurality of panels erected and fastened together to form a wall, tie members in said panels and having heads at the outer side of the panels, bracing members having reduced ends passed through said heads, and other bracing members aligned with the first named bracing members and having bored ends receiving said reduced ends.

2. A braced mold wall comprising a plurality of panels erected and fastened together to form a wall, tie members in said panels and having heads at the outer side of the panels, bracing members having reduced ends passed through said heads, other bracing members aligned with the first named bracing members and having bored ends receiving said reduced ends, and wedges driven between said panels andthe bracing members.

3. A braced mold wall comprising a plurality of panels erected and fastened together to form a wall, tie members in said panels and having heads at the outer side of the panels, bracing members having reduced ends passed through said heads, other bracing members aligned with the first named bracing members and having bored ends receiving said reduced ends, certain of said bracing members extending across the edges of said panels, and wedges driven between said panels and the bracing members.

In testimony whereof I aflixmy signature in the presence of two witnesses.
